The meter can also use manual salinity correction for dissolved oxygen readings
reported as mg/L . The manual salinity correction factor must be entered as ppt
(parts per thousand) .

Temperature Compensation and Reference Temperature
The Orion Star and Star Plus conductivity meters have the ability to use a
temperature compensation feature that calculates and displays the conductivity
measurements at a reference temperature of 5 °C, 10 °C, 15 °C, 20 °C or 25 °C
(Orion Star meters have a reference temperature of 15 °C, 20 °C or 25 °C only) .
The temperature compensation can be set as linear for most aqueous samples,
non-linear for ultra pure and low ionic strength samples or off for non-temperature
compensated conductivity measurements .
